Ian has been learning about different kinds of mixtures at school. While he was helping prepare dinner for his family, he noticed that some of the food they were making were different kinds of mixtures. What kind of mixture was their dinner if they were having spaghetti and meatballs? A. heterogeneous B. homogeneous C. solute D. suspension
The type of mixture if they were having spaghetti and meatballs for dinner is
a heterogeneous mixture.
Heterogeneous mixture involves two or more substances not having a
uniform composition in the mixture. The substances in the mixture are
usually differentiated easily.
In the case of the spaghetti and meatballs , there is no uniform composition
and they are easily differentiated which means that the mixture is a
heterogeneous mixture.

Explanation: Mine was a little bit different than yours please forgive me if I'm wrong I chose answers that was similar to mine
Methane burns in air that contains oxygen and Hydrogen gas and oxygen gas react explosively to form water. These two reactions are faster than the others.
What is methane ?Chemically speaking, methane has the formula CH4. The simplest alkane and the primary component of natural gas, it is a group-14 hydride. The amount of oxygen breathed from the air might be decreased by high methane levels. This may include headaches, facial flushes, slurred speech.
Unscented, colorless, and combustible, methane is a gas. It is mostly used as fuel to produce heat and light. It is also employed in the production of organic compounds. Methane is frequently found in landfills, marshes, septic tanks, sewers, and other places where natural materials decompose.
Suffocation can result from high methane concentrations in enclosed spaces because methane reduces the amount of oxygen in the air. Lack of oxygen can cause headaches, nausea, lightheadedness, and unconsciousness.
Thus, option A and D are correct.

What is the volume of 45g of benzene, C6H6 at 100°C and 250 Torr?
Answer:
V = 53.82 L
Explanation:
Given data:
Mass of benzene = 45 g
Temperature = 100°C (100+273 = 373 K)
Pressure = 250 torr (250/760 = 0.33 atm)
Volume of benzene = ?
Solution:
Number of moles of benzene:
Number of moles = mass /molar mass
Number of moles = 45 g/ 78.11 g/mol
Number of moles = 0.58 mol
Volume of benzene:
PV = nRT
V = nRT/P
V = 0.58 mol × 0.0821 atm.L/mol.K × 373 k / 0.33 atm
V = 17.76 atm.L /0.33 atm
V = 53.82 L

Which pair of orbitals has the same shape?
Your answer:
2s and 2p
2s and 1s
3p and 3d
more than one is correct
Answer:
2s and 1s
Explanation:
The s orbital is spherically symmetrical. The wave function depends on the distance from the nucleus and not on the direction.
The 2s and 1s orbitals are of the same shape only that the 2s orbital is larger than the 1s orbital.
The images of these orbitals are shown in the image attached.
The pair "2s and 1s" has the same shape. A complete explanation is below.
Throughout Mendeleev's table, the "s" orbital has a sphere as well as round symmetry. This same wave function would be determined by the difference again from the nucleus rather than the directions.These same 2s, as well as 1s orbitals, are approximately identical in form, with the exception being the 2s orbital appears bigger than the whole 1s orbital.
Thus the above alternative i.e., "option B" is appropriate.
